The ESD5Z5.0CT with TVS SOD-523 RoHS is a surface mount Transient Voltage Suppressor (TVS) diode manufactured by Yenji. It is designed to protect sensitive electronic components against electrical overstress. This component has a low leakage current and high surge capability, and is RoHS compliant, meaning it does not contain hazardous materials and meets the European regulations on the Restriction of Hazardous Substances. The diode has a ESD rating of 5kV, and can clamp voltage up to 5.0V. It is also characterized for EOS protection and fits in the SOD-523 package, a small surface mount part that requires minimal board space.
